Description
Technical Field
The present invention relates to a support jack comprising support feet and load cells according to the features of the preamble of claim 1.
Background
Such support jacks are generally attached to semi-trailers or trailers and support them on the ground, particularly when uncoupled from the towing vehicle. As a result, the semitrailer remains in a stable position in its parking space and can be accessed by the towing vehicle for recoupling. In other applications, support jacks are arranged at the rear of the silo vehicle and extend to stabilize the vehicle before the dumping process begins.
A support jack comprising a pressure element and a support load indicator is known from DE 10 2005 036 139A1, which support jack shows a safety position to an operator when the support jack is extended. The pressure element comprises a spring element, which is arranged between a spindle stop ring arranged in a stationary manner on the spindle and a spindle bearing plate, and a switching element in the form of a mechanical button which interacts with the spring element. When the support jack is extended, if the surface is stable, the main shaft moves against the main shaft bearing plate, deforming the spring element and actuating the switching element. The switching element is then connected to a display element which indicates to the operator the presence of the loaded support jack. However, it has proven disadvantageous that the spring element no longer delivers a reproducible value after frequent load changes, so that even an application of too low a force triggers the switching element. Furthermore, the support load indicator cannot be used to make any quantitative statement of the force transmitted by the support jack.
Disclosure of Invention
It is therefore an object of the present invention to provide a support jack which enables quantitative and reproducible measurement of the force transmitted from the support jack to the ground.
According to the invention, this object is achieved with the features of claim 1. By means of the load cells attached to the foot receiving element, it is possible to determine whether the trailer to be uncoupled is safely parked and, in particular in the case of semitrailers, whether the support jack is in firm contact with the ground. In addition to this qualitative determination, there is a quantitative determination of the load acting on the support jack. This makes it possible to determine the total weight of the trailer and thus the potential overload or uneven load distribution by registering the axle load.
The foot-receiving element is a component arranged in the flow of force between the support foot and the inner tube of the support jack. Typically, the foot-receiving element is firmly connected to the inner tube, in particular welded. As a result, the inner tube is additionally reinforced at its lower end by the foot-receiving element.
The load cell is a sensor that generates a signal proportional to the force introduced from the deformation of the foot-receiving member. These sensors are, for example, piezoelectric sensors which detect a change in the electrical polarization and thus the occurrence of a voltage on the solid when the solid is elastically deformed. Alternatively, capacitive sensors may also be used.
The force-measuring element is attached to the foot-receiving element, wherein it is preferred that the force-measuring element is fastened within the foot-receiving element or on a surface of the foot-receiving element. Common to all fastening positions is that the force-measuring cell is connected to the foot-receiving element such that the force-measuring cell detects deformation of the foot-receiving element as precisely as possible, wherein non-positive material and/or a positive connection (positive connecting) are particularly suitable, in particular by precise clamping or gluing. Using a force measuring element, the force can be determined depending on the deformation of the foot-receiving element.
According to a first preferred embodiment, the foot-receiving element has: a body by which the foot-receiving element is fastened to the inner tube; and two bearing pins protruding on opposite sides of the body. The body may be shaped complementarily to the inner contour of the inner tube, inserted into the inner tube from below and preferably connected to the inner tube in a material-bonded manner. In the axial direction, at least the lower section of the inner tube overlaps with the body inserted therein, which increases the overall wall thickness in the region of the load introduced by the support feet. The bearing pin engages on the body, for example. Particularly preferred are embodiments in which the bearing pin and the body form a one-piece, integrated structural unit. The support feet are pivotally attached to the bearing pins.
According to a second alternative embodiment, the foot-receiving element has a shaft tube which protrudes laterally beyond the inner tube and to which the support foot is pivotably attached. The shaft tube may be hollow or solid. The inner tube may be provided with corresponding, aligned openings to accommodate the shaft tube. It is also possible to insert the shaft tube into separate bearing sleeves which are then firmly connected to the inner tube and aligned with each other.
The bearing sleeve may be inserted into an opening in the inner tube or connected to the front end of the inner tube from below.
The load cell may then be attached to the body, to one of the bearing pin or the shaft tube.
The force-measuring element can in particular be pin-shaped and be inserted without play or under prestress into a complementarily shaped recess of the foot-receiving element.
A particularly useful embodiment is one in which the pin-shaped load cell is a measuring pin and the recess is a measuring pin hole into which the measuring pin is inserted. Measuring pin is understood to mean a force-sensitive sensor in the transverse direction, which is generally designed cylindrically and is always inserted with a precise fit and/or under pretension or at least in the presence of the expected operating load into a complementarily shaped measuring pin bore in the component to be measured. Pretensioning of the measuring pin is achieved, for example, by means of clamping devices integrated into the measuring pin. The diameter of the measuring pin hole is generally 6.00mm to 10.00mm, particularly preferably 8mm.
According to a particularly useful embodiment, the measuring pin is mechanically clamped in the measuring pin hole. This allows the measuring pin to be removed from the measuring pin hole and reinserted for maintenance and repair purposes. If the connection is cast or glued in the measuring pin hole, much more effort will be required to replace the measuring pin.
Advantageously, the recess is arranged in one of the bearing pin or the shaft tube. Both assemblies directly absorb the forces transmitted by the support feet and are therefore subject to shape changes under load, which are detected by the pin-shaped load cells.
Advantageously, the recesses are aligned in the axial direction of the bearing pin or shaft tube. This results in the advantage that the pin-shaped load cell is exposed to bending stresses on the bearing pins or axle tubes when the support foot stands on the ground, and that a particularly accurate measurement of the forces acting on the support jack is possible. The measurement accuracy can be even further improved on the side facing away from the outer tube and/or the inner tube if the recess is arranged eccentrically on the central axis of the bearing pin or the shaft tube. In this region, the bearing pin or shaft tube undergoes stretching, the amount of stretching increasing with increasing eccentricity, which further improves the measurement accuracy.
Conveniently, the recess is formed as a blind hole on one front side of the bearing pin or shaft tube. This makes it possible to position the pin-shaped load cell in the region of maximum applied force without weakening the bearing pin or shaft tube by an unnecessarily long recess.
Advantageously, the pin-shaped load cell is inserted into the deepest part of the blind hole. This results in a particularly protected installation position of the pin-shaped load cell.
The support leg can have a base plate on which two wall sections are formed which project laterally relative to the inner tube, wherein bearing openings are formed in the wall sections for receiving bearing pins or shaft tubes, at least one section of the pin-shaped load cell being arranged between the adjacent wall section and a plane of downward projection of the inner tube.
The flow of force takes place from the support foot via the wall section to the bearing pin or shaft tube and from there, if appropriate, via the body to the inner tube. In the region between the wall section and the inner tube or the downward extension of the inner tube, the bearing pin or shaft tube to be monitored by means of the pin-shaped load cell undergoes a maximum deformation, which makes it possible to measure the pin-shaped load cell particularly accurately.
According to a further alternative embodiment, the force measuring element is a strain gauge application. Strain gauge applications are used to record the tensile and compressive deformation of the foot-receiving element. Strain gage applications change their resistance even with very little deformation and act as strain sensors. Typically, strain gage applications are glued to a foot-receiving element that deforms minimally under load. Thus, deformation of the foot-receiving member under load causes a change in resistance of the strain gauge application.
It is preferred to attach strain gauge applications to the upper and/or lower side of the body. This gives rise to the advantage that the weakening of the foot-receiving element does not have to be performed by drilling or milling, on the one hand, and that there is an expansion or compression on the upper and lower side of the body, on the other hand, so that a particularly accurate and reproducible measured value can be achieved. Since the strain gauge application is regularly located on the surface of the component to be monitored, it is preferably attached to the body, in particular to the upper side of the body, which is protected inside the inner tube.
As an alternative to the above embodiments, the strain gauge application may be applied to the shaft tube and detect deformation of the shaft tube under load.

Detailed Description
Fig. 1 shows a longitudinal section through a support jack with an outer tube 20 in the form of a square profile and an inner tube 30 guided axially therein.
Due to the complementary contour shape of the outer tube 20 and the inner tube 30, the inner tube 30 is held in the outer tube 20 in a rotationally fixed manner in the circumferential direction.
To attach the support jack to the vehicle, mounting flange plates 23 protrude on both sides of the outer tube 20, wherein mounting holes 24 are made in the mounting flange plates 23 at discrete intervals. The inner tube 30 carries at its lower end supporting feet 60 by means of which supporting feet 60 the support jack stands on the ground when the inner tube 30 is extended.
Disposed within the outer tube 20 is a gear arrangement 50, the gear arrangement 50 having a spindle 52 rotatably mounted relative to the outer tube 20 and a gear 51 connected to the spindle 52 in a rotationally fixed manner at an upper end section. By rotating the spindle 52, the spindle nut 31, which is firmly inserted into the upper section 32a of the inner tube 30, is moved downward or upward, depending on the direction of rotation. When the spindle nut 31 moves downward, the inner tube 30 and the support legs 60 attached thereto are pushed toward the ground and the support jacks protrude. When the spindle nut 31 moves upward, the inner tube 30 is lifted up together with the support legs 60, and the support jack is retracted.
The spindle 52 passes through a spindle bearing plate 21 arranged below the gear 51, wherein the spindle bearing plate 21 is formed with a spindle opening 22, the inner diameter of which is selected to be only slightly larger than the outer diameter of the spindle 52. By means of the spindle bearing plate 21 and the spindle opening 22, the spindle 52 is supported in its radial direction. The spindle bearing plate 21 is firmly connected to the inner wall of the outer tube 20 on at least three sides, preferably on four sides. The spindle bearing plate 21 is oriented substantially orthogonal to the extension of the outer tube 20. The spindle 52 and the associated spindle opening 22 in the spindle bearing plate 21 are centrally accommodated in the outer tube 20.
Fig. 2 shows the lower section 32b of the inner tube 30 with support feet 60 attached thereto. The support foot 60 is pivotally mounted on the foot-receiving element 40, which foot-receiving element 40 is then fixed in a stationary manner to the inner tube 30 in the region of the lower section 32 b. In the exemplary embodiment shown, the foot-receiving element 40 has a main body 41 and two bearing pins 43 protruding on opposite sides with respect to the inner tube 30. Bearing pins 43 project laterally outwardly below the inner tube 30 and/or the outer tube 20.
The body 41 is formed with a shape complementary to the inner contour of the inner tube 30, inserted into the inner tube 30 from below at the end face and permanently connected thereto. In the maximum raised position of the inner tube 30, the bearing pin 43 abuts the end face of the outer tube 20. Typically, the body 41 at least partially overlaps the inner tube 30 from the inside and protrudes downwardly from the inner tube.
The support foot 60 comprises a substantially planar base plate 61 on which two vertical wall segments 62 are formed. The inner tube 30 and the outer tube 20 are arranged between two wall segments 62. Each wall section 62 has mutually aligned bearing openings 63 through which the bearing pins 43 of the foot-receiving element 40 extend, wherein the bearing pins 43 on the right side in the image plane are of two-part construction for simplifying the mounting of the support foot 60 on the foot-receiving element 40 and have detachable assembly end pieces 43a which are fastened to the bearing pins 43 by means of screws 43 b. When the support foot 60 is mounted on the foot receiving member 40, the support foot 60 swings about the central axis x of the bearing pin 43.
A recess 42 extending parallel to the central axis x is introduced into a front side 44 of one of the two bearing pins 43, which recess 42 can be, for example, a measuring pin hole 42.
In the present exemplary embodiment, the recess 42 is designed as a blind hole 45, the bore hole deepest 46 of which blind hole 45 extends to a downwardly extending projection plane y in the extension of the inner tube 30. The load cell 10, in particular the measuring pin 11, in the form of a pin-shaped load cell 10 is inserted in a stationary manner into the recess 42 and is clamped in the recess 42 relative to the associated bearing pin 43.
The pin-shaped load cell 10 is located in the region between the nearest wall section 62 and the deepest borehole 46. When the inner tube 30 protrudes relative to the outer tube 20 and the support foot 60 stands on the ground, a force flow occurs from the support foot 60 to the inner tube 30 via the bearing pin 43. As a result, the bearing pin 43 between the wall section 62 and the body 41 is subjected to bending stresses and is deformed relatively greatly, which enables an accurate measurement by means of the pin-shaped load cell 10 and the measured values thereof can be attributed to the corresponding supporting loads.
In fig. 3, the lateral overlapping of the wall segments 62 with the outer tube 20 and the inner tube 30 is particularly well visible in the retracted position of the support jack. In the extended position of the support jack, the wall section 62 only overlaps the inner tube 30.
Both fig. 2 and 3 show the eccentric orientation of the load cell 10 within the bearing pin 43. Due to the bending stress under load, the load cell 10 is located on the side of the bearing pin 43 facing the bottom plate 61, which is subject to a greater elongation with increasing eccentricity with respect to the central axis x.
The transition coupling 13 is inserted into the open end of the recess 42, the recess 42 is closed off from the outside by means of the transition coupling 13, and only the connection cable 14 is led out of the recess 42 via the transition coupling 13. The load cell 10 is electrically connected via a connection cable 14 to an on-board network of the vehicle, not shown here, from which electrical energy is supplied to the load cell 10. Furthermore, the load cell 10 provides a load signal to the vehicle via the connection cable 14.
Fig. 4 shows an alternative embodiment of a load cell 10 in the form of a strain gauge application 12. Preferably, the strain gage application 12 is applied to the upper side 41a of the body 41 and is located in a protected position within the profile of the inner tube 30. In principle, it would also be possible to attach the strain gauge application 12 to the underside 41b of the body 41, however, which is exposed to considerable environmental influences while driving.
The strain gauge application 12 may be connected to the energy and data system (not shown here) of the vehicle by means of a connection cable 14.
Fig. 5 shows a further embodiment of the support jack, in which the foot-receiving element 40 comprises a shaft tube 47. The shaft tube 47 is a continuous assembly having a circular cross section. The shaft tube 47 passes under the opposite wall section of the inner tube 30 to such an extent that the bearing opening 63 of the wall section 62 is also penetrated by the shaft tube 47. The support foot 60 is pivotally mounted on the shaft tube 47.
In order to stiffen the lower section 32b of the inner tube 30 and to reduce the surface pressure in this region, bearing sleeves 48 are firmly attached to the inner tube 30 in alignment with each other, through which bearing sleeves 48 the shaft tube 47 passes. The axial alignment of the two bearing sleeves 48 is substantially perpendicular to the axial extension of the inner tube 30.
A load cell 10 in the form of a strain gauge application 12 is applied on the surface of the shaft tube 47. In the present exemplary embodiment, the strain gage application 12 is located on the side of the shaft tube 47 facing the bottom plate 61 of the support foot 60. It is particularly preferred that the strain gage application 12 is disposed between the wall segments of the inner tube 30, particularly between two spaced apart bearing sleeves 48.
Fig. 6 shows a further exemplary embodiment of the invention having a foot receiving element 40 in the form of a shaft tube 47, the wall thickness of which has a sufficient thickness to provide a recess 42 therein, in particular a measuring pin hole 42. The pin-shaped load cell 10, in particular the measuring pin 11, is inserted into the recess 42 and is releasably clamped therein. The recess 42 is located on the side of the shaft tube 47 facing the bottom plate 61.
Furthermore, the recess 42, which is also designed as a blind hole 45, opens at the front side 44 of the shaft tube 47 and ends with its bore hole deepest 46 overlapping the adjacent bearing sleeve 48. In this respect, in the exemplary embodiment, at least one section of the pin-shaped load cell 10 is located between the wall section 62 of the support leg 60 and the projection plane y in the extension of the inner tube 30.
